I think that's the plan-- to wean the human diet down to Soilent Green.
There's actually a company that manufactures plant-based food named soylent (for soy and lentils)
I know of that product. Bizarre product naming seems to be trendy among the hipsters. A few years ago, I saw a beaded Christmas garland labeled "Sophie's Choice." Took it to the store manager and she was on the phone in minutes to the corporate office to complain.
